1 kg of Tumbled Dinosaur Bone - Small Responsibly sourced and geologist certified tumbled stone, perfect for jewelry-making, crafting, pocket stones, and more! This Tumbled Dinosaur Bone was certified in the Geoworld Geo-paleontological laboratory in Italy under the supervision of expert geologist, Dr. Stefano Piccini. Origin: Madagascar Chakra: 1st (Material Body), 2nd (Creativity & Personality), 6th (Conscience) Zodiac: Aries, Leo, Capricorn Formed over 100 million years ago, Dinosaur Bone is the mineralized remnant of once-living ancient creatures. Through a process known as permineralization, the organic bone structure is gradually replaced with chalcedony, jasper, or agate, preserving the cellular matrix in striking detail. The result is a dense, richly patterned fossil, often displaying hues of deep red, earthy brown, cream, and black—each a geological fingerprint of time. Images are approximations; product varies naturally in size, shape, and color.
